IMPROVEMENT in AXES.

Specification forming part of Letters Patent No- 184,799, dated November 28, 1876; application filed May 9, 1876.

To all whom it may concern Be it known that 1, JOHN 0. Bonus, of Truckee, in the county of Nevada and State of California, have invented an Improvement in Axes, of which the following is a specification:

In the accompanying drawing, Figure 1 rep resents a side view, Fig. 2 a top view, and Fig. 3 an end view, of my improved ax with bit detached.

Similar letters of reference indicate corresponding parts.

My invention relates to an ax having detachable bits that may be readily interchanged and securely attached, so as to admit the use of one ax with thick or thin bits, for difl'erent purposes, and the replacing of dull bits by sharp ones.

The invention will first be described in connection with drawing, and then pointed out in the claim.

In the drawing, A represents the body of the ax, and B the detachable bits. The body A may be made of cast-iron, if desired, which admits the cheaper manufacture of the axes. The ends of the body A are provided with tapering or concave grooves, or with beveled or convex edges, to which the corresponding beveled or recessed bits are fitted, both methods being shown in Fig. 1. The middlepart of the ax-body is centrally recessed back of or extended beyond the slightly-inclined side parts, the bits being in the same manner made with a central extension or recess, so as to be connected to the ax, and thereby protected against lateral displacement, as indicated in Fig. 1. When the bits are placed in position they are locked against displacement in the longitudinal direction of the ax by rivets G of soft meta-1, that are driven in tightly to retain the bits securely on the ax. The rivets may be easily removed by a steel punch for the purpose of replacing dull or broken bits, or

inserting bits of diiferent size for difi'erent work, as required.

The rigid fastening of the ax and bits by the joint action of the concavo-convex edges of the interlocking middle parts and of the rivets secures a superior connection of the JOHN 0. ROLLINS.
